WINDOW.

SPECIFICATION forming part of Letters Patent No. 424,179, dated March 25, 1890. Application filed September 5, 1889il Serial No. 328,025. (No model.)

.To all whom it may concern;

Be it known that I, JOHN P. CLARK, Jr., of Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Improvement in lVindows, of which the following is a full, clear, and exact description The object of my invention is to provide an improved means for adjusting, sealing, and securing the sashes of a window in their casement or frame.

`To this end my invention consists in the construction and combination of parts, as hereinafter describechand indicated in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding partsin all the figures.

Figure l is a front elevation of the inside of a window and its frame. Fig. 2 is a secv tional side elevation of the window, taken on the line 2 2 in Fig. l. Fig. 3 is aisectional plan view of the window and its frame, taken on the line 3 3 in Fig. l; and Fig. 4 is an enlarged detached view of a side rail of the window, in section on the linett in Fig. l, showing the preferred method of securing the glass in the window.

The frame of the window is composed of the stiles A, eap-piece A and subsill A2, joined together in the usual manner. rlhe inner faces of the stiles A are furnished with beadstrips a a', secured thereto, forming abutments for the sash-frames and shutters,

thelatter named being omitted from the drawings. The upper and lower sash-frames are constructed in a similar manner; hence it will be sufficient to describe one, which will answer for the pair. Each frame consists of the side bars I), held together by top rails b and bottom rails b2. On the inner edges of the frame longitudinally-grooved strips c are secured. The grooves therein receive and retain a metal frame or shoe c', (see Fig. 4,) which shoe is adapted to encompass alight of glass B. A suilicient space is permitted between the double parallel walls of the shoes c to permit continuous lgum washers c2 to be intro` duced on each side of the light of glass B, so that said sheets of glass will be relieved of strains and avoid breakage that might result Vfrom expansion of the glass, contraction of `the frame, or other causes of similar nature.

The upper rails b in each sash are notched, as at (Z,`so that overlapping ends d are produced, which bear upon the ends of the shorter side barsb, and are secured thereto by screws,

which retain all in place.

The upper and lower sash-tI rames are so proportioned to the dimensions of the windowparts intact after the glass is frame that they will neatly tit therein when hinged together on the inner surface thereof,

as at 7L, which will permit the lower or upper sash to be swung inwardly.

When both sashes are closed, the upper sash is secured from falling inwardly by a spring-catch t', that engages a latch-plate i', which is secured to the lower surface of the cap-plate A', a downward movement of the bolt of the catch releasing the upper sash'in an obvious manner.

An inward inclination at any desired angle may be afforded the upper sash by the proper location of the slotted linksm., which are pivotally afiixed by their lower perforated ends m to the stiles of the window-frame, their slotted upper portions engaging the inserted screw stops or pivots n, which are embedded in the edges of the side bars b of the sashframe.

The lower sash when opened can be upwardly folded against the upper sash and there retained by a spring-catch k, that is secured on the inner face of the cap-piece A of the window-frame, a wear-plate 7c on the outer face of the lower rail Z22 engaging said catch 7c when. the lower sash is so adjusted.

In order to provide for the secure closing of the lower sash and prevent cold air or dust from entering the apartment, a cap-sill C is mounted upon the subsill A and thereto secured so as to have a limited vertical vibra- IOO tion by the longitudinally-central screw 0, which is inserted in a slightly-elongated oritice in the cap-sill and firmly introduced into the sub-sill.

The cap-sill C is provided with a depending skirt-piece C', that forms a finish for the window-sill on the inner face of the same, and to press the cap-sill C upwardly against the lower edge of the lower sash-frame in a yielding manner the springs p are secured upon the sub-sill A2 below the cap-sill, against which they impinge, so as to aiford an elastic seat therefor, which provision will effectually close the crevice below the lower sash and by pressure against the inner edge of the sash seal the Window at this point against inward draft of cold air or intrusion of dust,

Having thus described niyinvention, Iclaini as new and desire to secure by Letters Patentl. The combination, with a window-frame having Vertical bead-strips attached and projecting from the sides oppositely, of two sashlsash-frame, a spring-catch for the top sash latchin g upwardly, aspring-catch for thelower sash latching downwardly, and two slotted 2. The combination, with a window-frame and two sash-frames hinged together, the meeting edges of the sash-frames being rabbeted to afford mating offset shoulders, and a spring-catch for each sash-frame, of ltwo slotted link-bars pivoted to the window-frame and to the upper sash-frame, so that the upper pivots mayslide in thelink-slots, substantially as set forth.

3. The combination, with a window-frame and two sash-frames hinged together, of a yielding cap-sill which bears upwardly against thelowersash-frame, substantially as set forth.

Lt. The combination, with a window-frame and two sash-frames, of a cap-sill loosely secured to the sub-sill of the window-frame, and a spring-support for the cap-sill, substantially as set forth.
